10090. 'And it shall be the portion for you' means transmission to those who are governed by God's truths. This is clear from the representation of Moses, whose portion the breast was to be, as the Lord in respect of Divine Truth, thus Divine Truth which comes from the Lord, dealt with in 6752, 7010, 7014, 9372; and from the meaning of 'being the portion for' as transmission, since those parts of sacrifices that were given to Moses, Aaron, his sons, and the people were signs of the transmission of what was Divine and holy with them. And all transmission takes place in accord with the character of the recipient, thus in accord with the character of the representation among those who were the recipients.

[2] The reason why the breast was apportioned to Moses and the flank, spoken of a little further on, to Aaron was that the subject at present is the transmission of Divine Truth and Divine Good from the Lord in heaven and in the Church, and their making that Truth and Good their own. These two - Divine Truth and Divine Good, both of which come from the Lord - are what are received there, Divine Truth by those in the Lord's spiritual kingdom and Divine Good by those in the celestial kingdom, see the places referred to in 9277, 9684. This explains why the breast was apportioned to Moses and the flank to Aaron, for 'the breast' means Divine Truth in the Lord's spiritual kingdom, 10087, while 'the flank' means Divine Good in the celestial kingdom, 10075, as also does 'the bread in the basket', which too was assigned to Aaron, 10077.

[3] As was shown just above, Moses represented the Lord in respect of Divine Truth; and Aaron, when consecrated to the priesthood, represented the Lord in respect of Divine Good, see 9806. The fact that the breast was assigned to Moses as his portion is clear in Leviticus, where again the consecration of Aaron and his sons to the priesthood is the subject,

Moses took the breast and waved it as a wave offering before Jehovah, from the ram of fillings [of the hand]; and it was Moses' portion, as Jehovah had commanded Moses. Leviticus 8:29.

6751. 'And he was a son to her' means that then first truths were attached to that affection. This is clear from the representation of Pharaoh's daughter, to whom 'to her' refers here, as an affection for factual knowledge, dealt with immediately above in 6750; and from the meaning of 'son' as truth, dealt with in 489, 491, 533, 2623, 3373, here first truth since 'being a son to her' is possessing first truths acquired through factual knowledge. For first truths are born from factual knowledge and so are like sons born from their mother, who is the affection for factual knowledge. And factual knowledge is the groundwork for truths composing the understanding and faith, see above in 6750. When a person is being regenerated matters of faith develop in him in almost the same way as things that are not matters of faith develop while he is growing up. While he is growing up sensory impressions compose the first level to be laid down, then known facts another level; and after that, grounded on these levels, the power of judgement grows, more fully with one person, less fully with another. While a person is being regenerated the general aspects of faith or the basic elements of the Church's teachings compose the level that is laid down first, then come particular aspects of that teaching and faith, and after that in successive stages things that are more and more internal. These are levels which the light of heaven shines on; and from this comes the power of understanding, and the ability to perceive the truth of faith and the good of charity.
